Definitions

  • the present invention relates to a method and a system for monitoring the failures of at least one light radiation source, more particularly suitable for monitoring a plurality of public lighting sources.
  • the present invention aims to overcome these drawbacks.
  • the invention firstly relates to a method for monitoring the failures of at least one source of light radiation, in which the radiation possibly emitted by said source is detected using a photocomponent. a period when it is energized, characterized in that a fault signal is emitted on the source supply line, in the absence of detected radiation, and that said fault signal is picked up at a point on the line distant from said source.
  • Monitoring can thus be carried out in real time during network use, and remotely, which is a first advantage.
  • modern public lighting networks are generally constituted by light discharge bulbs powered by ballasts, so that, in certain cases, an extinguished bulb continues to absorb a non-negligible current.
  • the invention therefore makes it possible to overcome this difficulty, linked to detection by observation of the absence of absorbed current.
  • the failure signal is emitted after the sources are energized, after a time as a function of a serial number of the faulty source in this plurality of sources.
  • this function can be a linear relation.
  • a signal is emitted on the supply line, the signal corresponding to a particular source being emitted after an additional time equal to the product of an elementary time by the serial number of the source considered.
  • the failure signal is emitted after the detection of the failure of one of the sources, for a time as a function of a serial number of this source in the plurality of sources.
  • the time during which the failure signal is emitted corresponds to a given source is for example proportional to the serial number of this source, so that it is sufficient, when a failure signal is detected on the supply line , measure the duration of this signal to deduce the serial number of the corresponding source.
  • the two modes of implementation described above can be combined, the first mode being used during powering up of the network in order to detect all the sources already failing at this instant, then a switching taking place for switch to the second mode in order to detect new failures in real time.
  • the identification of a faulty source is carried out either from the time of arrival of the corresponding signal, or from the duration of this signal, it is very simple to use as a failure signal a monofrequency signal , for example of musical frequency.
  • Such a signal can be much more easily superimposed on the supply current of the sources than a digital coded signal. Finally, its detection on the supply line presents no difficulty since a simple single filter makes it possible to detect all of the signals corresponding to all the sources of the network.
  • the failure signal is captured using an automaton which transmits this signal over a telephone line, for example to a control station.
  • the present invention also relates to a system for monitoring the failures of at least one source of light radiation, comprising a photocomponent arranged to supply an electrical signal when said source emits radiation, characterized in that it comprises means for emission likely to emit a failure signal, on the supply line for said source, and control means for controlling the transmission means in the event that no electrical signal is supplied by said photocomponent.
  • this photocomponent is connected to the radiation source by an optical fiber.
  • the source is constituted by the bulb of a street lighting candelabra
  • the source is constituted by the bulb of a street lighting candelabra
  • the transmission means may, in a particular embodiment of the invention, comprise an oscillator, in particular of musical frequency.
  • control means can be connected to the transmission means by means of timing means, and arranged to cause the transmission of the failure signal after a time after a predetermined time, such as when the sources are energized, and / or for a time after detection of the failure of one of the sources, which are a function of a serial number of the faulty source in said plurality of sources.
  • the system according to the invention can also include an automaton at a point on the supply line remote from said source, arranged to pick up the fault signal and transmit it over a telephone line.
  • the candelabra of FIG. 1 comprises an optic 1 in which is mounted a bulb 2, for example with light discharges, and a tubular support 3.
  • An optical fiber 4 is arranged in the support 3 with one of its ends in the optical 1 in the vicinity of the bulb 2 and its other end connected to an electrical box 5 which will be described with reference to FIG. 2.
  • a power line 6 allows on the one hand the electrical supply of the bulb 2 and of housing 5, and on the other hand, the transmission of a fault signal when the bulb 2 is energized but not lit .
  • FIG. 2 shows in 7 the derivation of the line 6 allowing the supply of the bulb 2 via a cable 8, and of the housing 5 via a stabilized supply 9.
  • a photocomponent 10 for example a photodiode, is placed at the lower end of the optical fiber 4, and its output current is amplified in an amplifier 11.
  • the output voltage of the amplifier 11, which is therefore representative of the on or off state of the bulb 2, is applied to a timing circuit 12 controlled by a logic control unit 13 as will be described below. afterwards, so as to control in turn an oscillator 14 of musical frequency.
  • the output of this oscillator for example at a few hundred Hz, is applied to the branch 7 via a filter 15 so as to then be transmitted on line 6.
  • each logic 13 of the different candelabras connected to the line blocks the device for a time T1 sufficient to allow the ignition and ignition of all non-faulty bulbs 2 connected to the line 6.
  • the time T1 can for example be of the order of 120 seconds.
  • the logic unit 13 continues to block the device for a time T2, proportional for example to the serial number of the candelabrum relative to the origin of the line 6.
  • the logic unit 13 causes the emission by the oscillator 14 of a failure signal , of a short duration but sufficient for the signal which will be received on line 6 to be clearly identifiable, without, however, that two signals corresponding to contiguous candelabra may overlap.
  • the time T2 can be chosen to be equal to 0.4 ⁇ N seconds, where N is the serial number of the candelabrum, while the failure signal is emitted for a duration of 0.2 seconds.
  • the network carries for example 200 candelabras
  • the network carries for example 200 candelabras
  • the logic units 13 cause the timing system to switch to a second operating mode, making it possible to detect faults occurring during service.
  • T ⁇ 0.2 x N seconds.
  • FIG. 3 represents the device installed at the public lighting station and responsible for detecting, analyzing and transmitting the failure signals.
  • the voltages on these lines are filtered using filters 16, 16 ⁇ , .... 16 ⁇ so as to detect the failure signals in musical frequency emitted on the supply lines by the various failure detection devices such as 5.
  • the signals thus detected are rectified in 17, 17 ⁇ , .... 17 ⁇ and amplified in 18, 18 ⁇ , .... 18 ⁇ .
  • the fault signals thus detected and processed are then analyzed by a programmable controller 19 which determines the faulty sources and retransmits the information collected on an alert network 20, for example the switched telephone network, to a monitoring station.
